If the CPUs are soldered to the daughtercards, it'd be quite difficult. If not, it still might be no-go, as the higher speed may need some ancillary chips to be higher speed as well. You could probably exchange daughtercards of different speeds, though... Oh, and the 433MHz is also a 21164A, aka EV56, just slower. > So have I hit the PYXIS DMA crossing page boundary bug here?

Definitely, the 433 is an early MIATA and thus doesn't have all the "Pyxis fixes" that a MIATA-GL (latest) would have, and so could indeedbe susceptible to the DMA bug... :-\ > The reason for going to IDE is that the Qlogic scsi card only wants to > see narrow scsi drives, not wide.

MIATA Qlogic cards were typically 1020-based, which is only narrow, IIRC. If you do have a 1040-based controller, that should do wide, and may depend on the cable and/or termination.
